The guns are then con nected to the traveling carriage byrmeans of a detachable clip A and as the brackets A of the lifting screws "A are not disengaged. from the pivot'pins ortrunnions A? the gun mounting as'a Whole is then ready for being transported by the traveling carriage. The said lifting screws are preferably so {situated on the, traveling carriage that wheny'the mounting occupies its traveling pos tion the,

' To bring the gun mounting from the traveling position to the firing position'the clip A is removed, the mounting is swung about c the pivotlpins. or trunnions A until the base A is parallel to the ground, the lifting screws A ;areloperated to-lower the mounting so that the'bas'e A rests on the ground, the brackets A are detached frointhepivot pins ortrunnionsA andthetransoin B? is swung to one side.
